Emails don't arrive to Hotmail accounts


New Member

I have more than one year sending a newsletter every sunday to more than 10k registered users.

Today my newsletter don't arrive to any Hotmail account (to other accounts work fine). I did tray using different email senders accounts located in the same server and didn't work too, but from another server and another email account work fine (using HTML only).

From Mac Mail app I can send any email from any account to hotmail, this only happend using Maxbulk Mailer 5.8

Please, how I can check if my server is in a blacklist? Please help me!

Have you sent a lot of emails to hotmail? They can block you either whether you send a lot of messages or use many dead hotmail addresses.

Yes, maybe something like that happens.

I have only a few weeks using the Email Bounce Handler and I notice that I have 3k emails bounced.

Please, you can point me to the right direcction to solve that?

This is an example of a returned undelivered email:

I am not sure how to handle Hotmail blocks actually. Perhaps paying them a great sum of money?
